ORGAN-CASE.

SPECIFICATION forming part of Letters Patent No. 349,656, datedSeptember 21, 1886.

Application filed June H, 1886. Serial No. 205,089.

To aZZ whom it may concern:

Be it known that" I, ELMER H. LORING, a citizen of the United States,residing at \Vorcester, in the count of \Vorccster and State ofMassachusetts, have invented certain new and useful improvements inPedal-Cover-Operat- 'ing Mechanism, of which the following, to getherwith the accompanying drawings, is a specification snt'ticiently l'ull,clear, and exact to enable persons skilled in the art to which thisinvention appertains to make and use the same.

The object ol' this my present invention is to provide a simple andetficientconnection, whereby the pedalcover in. an orgalrcase can beautomatically operated by movement of the tall, said connectingmechanism beingsnch that itcan be economically manufactured andconveniently arranged in the organ case without interfering with otherparts of the organ action; also to provide a fall-swing ofpecnliar formwhich will not interfere with the end of the brace where it meets theside of the case. These objects I attain by mechanism, the na ture ofwhich is herein shown and (lCSCl'ibOtl.

In the drawings, Figurel is a sectional view showing the arrangementofmy improved pod al-coverbpta'atingmeclianismwithintheorgancase. Fi 2is a horizontal section of the same. Fig. 3 is a vertical sectionthronghthe sheaves and bracket at the side of the pedal-space, and Fig.4 is a longitudinal section through the axis at one end of thepedal-ctwer roll.

In referring to parts, A indicates the organcase, of usual form, withbrackets or pilasters a on the front, at the sides of the pedal-space.13 indicates the pedals; G, the action; E, the brace, which extends fromend to end of the case, and F the fall or cover which closes and opensthe manual, all of which parts may be of ordinary or any suitableconstruction. The tall F is h inged to the fall-swing D, which latter Imake in a curved form, as shown in Fig. 1, and with an onset, as at (I,so that the lower part of the curve is at some distanceback from thepivot c, whercon the swing-arm D is pivoted to the end of the case. Bymaking the l'allswing in the oliset and curved form shown, theinterference thereof with the end of the brace E, where it is attachedto the end of the case, is avoided, and the necessity of cutting (Yomodel.)

into the braceto form space therefor,and thus weaken the stock of thebrace, is obviated.

H indicates the pedal-cover, connected with a roll, 71, the ends ofwhich are supported in the brackets a, so as to form a hinge on whichthe cover H swings up and down when open ing and closing the space infront of the pedals 13. Upon the endot' the roll 71,lattach asheave,Lwhich is preferably located within a mortise, a, formed in one of thebrackets, (4. Along the interior of the cast-I arrange a shaft or rod,K, rotatable in suitable bearingsfl, and provided at one end with asheave, J, and at the opposite end with a crank, K, substantially asshown in Fig. 2. A band, in, connects the sheaves I and J. (See Fig. 3.)Said band is fixed to the periphery of the sheaves with a suitableFastening-device, as at n, so that when the sheave J is turned thesheave I will also be turned, and the roll h and cover H will be therebyoperated. A rod or bar, 1, connects the crank K with the fall-swing D,inthcnianner illustrated by Fig. 1. Said rod is in the present instancemade in two parts, wit-h a right and left screw-tln'eaded adjListing-sleeve, t'or shortening or elongating its length; but, ifpreferred, it might; be made without means of adjustment.

The opcrati on is as indicated by dotted lines in Fig. 1. XVhen thefall. F is raised and slipped back into the case for opening thcmannal,the backward and to rward movement of the curved or offset portion ofthe tall-swing, to which the rod 1 is pivoted, depresses the crank K bymeans of the red I, thereby effecting partial r0 tation of the shaft Kand sheave J, which, by means of the band on, operates the roll h toswing the cover H'to its elevated position, as will be readilyunderstood from the inspection of drawings.

In some instances, in lieu of connecting sheaves J and I by means of theband m,it may be desirable to make the connection by means ofspur-gcarsthat is, the wheels I J, being provided with teeth, and anintermediate toothed wheel being arranged between them for connectingand transmitting the motion from the shaft K to the roll h.

The advantages of my invcnti on are that the mechanism can bemanufactured at a comparativcly small cost, conveniently applied to use,

and does not interfere in any manner with. the ordinary construction andarrangement of the organ actions.

I am aware that means for automatically operating a pedal-cover inconnection with the fall has been heretofore employed in an organcase,and I do not therefore herein make claim, broadly, to such feature. Sofar as I am aware, however, the mechanism forefi'ecting such operationis of an essentially difl'erent nature from that herein described.

What I claim as of my invention, and desire to secure by Letters Patent,is

1. The fall-swing arm curved and ofTset in the manner set forth, incombination with the brace and fall in an orga11-case,'as and for thepurpose specified. I

2. A pedal-cover mechanism consisting of the cover H, having ahinging-roll, h, at its edge, provided with a wheel fixed thereto, incombination with a rotative operating-shaft,

K, provided witha wheel, J, and devices for connecting and transmittingmotion betwem said wheels, whereby rotation of said shaft effects theelevation or depression of said cover, substantially as set forth.

3. The combination of the fall F, the fallswing D,the crank-shaft K,supported in bearings on the ease-and provided with a sheave,- J, therod P, connecting the fall-swing and the crank K on said shait, thepedal-cover H, provided with a sheave, I, axially coincident with thehinging of said cover, and aband, m, connecting said sheave with thesheave on said crank-shaft, substantially as and for the purpose setforth.

Witness my hand this 10th dayof June, A. D. 1886.
